Test failure on Windows

I've been able to compile echoprint extension with MSVC after these patches:

However test fails:

My compile generates signature with 245 characters, while test asserts equal signature with length of 145 characters.

Can someone point the reason for this failure?

Thanks

Start with tests.py and reproduce test_codegen on Windows using the reported setup.py configuration. Compare the generated signature with the expected value and inspect echoprint.cpp plus the listed libcodegen sources to identify the platform-dependent difference; done means the test passes with the intended signature on Windows.
